i I Application filed June 18, 1904- Serial No. 212.822.

To all whom it may concern:

Be it known that I, HERMANN G. PAPE, a

- citizen of the United States, residing at New ment, the object being to produce in the smallest possible compass an instrument which may be used either as an earpiece for audlphone sets or as a massage device or the treatment a sectional view of my instrument.

of a patient having impaired hearing.

To the accomplishment of this object the preferred embodiments of the invention reside in those constructions and arrangements to be hereinafter described, illustrated in the accompanying drawings. and succinctly defined in the appended claims.

In the accompanying drawings, Figure 1 is Fig. 2 is a sectional view of the same subject-matter on the line 2 2 of Fig. 1. Fig. 3 is a sectional elevation on the line 3 3 of Fig. 1. Fig. 4 is a detail sectional view of the magnet detached. Fig. 5 is a face view of the diaphragm. 6 is a'sectional view thereof. Fig. 7 is a diagrammatic view of the arrangement shown in Fig. 1. Fig. 8 is a sectional view of a modilied form of the invention. Fig. 9 is a diagrammatic view of the arrangement shown in .and 4.

Fig. 8, and Fig. 10 is a diagrammatic View of another modification.

Ll ke characters indicate corresponding parts in the several views.

- 1 indicates a casing preferably constructed of hard rubber and divided by a partitionwall 2 into front and rear compartments 3 The front compartment4 is closed by a cap-piece 5, secured upon the casing and having a concave front face Send an axial aperture 7, as usual. The rear face 8 of the cap IS also slightly concwve, asshown, and disposed adjacent thereto is a metallic diaphragm 9. peripherally weakened by a plurality of narrow slots l0 equidistant from the axis of the diaphragm and disposed tangentially toa circle concentric therewith. These slots 10 are preferably three in number and, as shown in Fig. 5. are arranged to correspond substantially with the alternate edges of a hexagon having its center at the axis of the diaphragm.

As it is of course well understood that the point of the diaphragm most sensitive to vi- Fig. I

braticn is the center thereof, it will readily appear that the provision of these slots well any material of greater flexibility than that .of the diaphragm. The means employed for the peripheral retention of the diaphragm is not material; but it may be held by screws 12, which serve to hold it independently of the cap 5, thus permitting the latter to be ad: .justed toward or from the diaphragm for the purpose of regulating the distance between the latter and the ear in accordance with the desires of individual users.

Opposed to the rear side of the diaphragm at the center of the instrument is a magnet 13, comprisinga shell 14:, an axial core 15, and an interposed coil 16, wound upon the core and designed to magnctize both the core and shell when acircuit is closed through the coil. The shell 14 is externally threaded and is retained within an axial opening 17 in the wall 2 by adjusting-nuts 18 and 19, screwed upon the shell beyond opposite sides of the wall 2 and opposed to wear-plates 20, between which and the opposite faces of the wall 2 are interposed soft-rubber gassets 21. This character of retaining means for the magnet is provided in order that slight endwise adjustment of the latter may be readily secured, it being noted that by screwing up one or the other of these nuts slight end wise adjustmcntof the magnetmay be effected for the purpose of regulating with great nicety the relation of the magnet and diaphragm.

In ordinary forms of telephone-receivers the magnet is arranged in the transmitting-circuit to vibrate the diaphragm; but by reason of the dual nature of my instrument it is necessary for the magnet to perform a dual function. This function is the actuation of an interrupter 22, which serves, when the device is used as an aural massage instrument,to repeatedly interrupt the .circuit through the mag-net in a. manner and for a purpose to be explained.

The interrupter 22 comprises a pair of contact elements 23 and 24, the former preferably having the form of abinding-post and the latter being defined by the end of an'armature sprlng 24, secured to an armature 25, opposed to the rear end of the magnet and located within the rear compartment 3 of the casing.

spring 29. having its opposite extremity se" cured to the wall 2 by a binding-screw 30, as shown in Fig. 3. The interrupter 22 is-normally closed and the circuit-closer normally open, as shown.

The back of the casing 1 is closed by aback plate or wall 31, through which is passed a push-pin 32, opposed at its inner end to the movable contact 28 of the circuit-closer. and provided at its outer end with a push-button 33, located exterior to the casing. The button 33 may be pressed by the finger of the operator to operate the circuit-closer, and th us close the circuit through the instrument when it is desired to use the latter. Preferably, however, the circuit-closer is disposed for automatic actuation. For this purpose the usual head-band 34 is provided with an extension 35, opposed to the button 33, and having at its lower extremity a hook 36, disposed to engage the keeper 3?, carried by the wall 31. The engagement of the hook and keeper efi'ect a pivotal connection between the head-band and the instrument, so that when the band is placed upon the head with the instrument in contact with the ear the pin 32 will be automatically moved in to bring the contacts 27 and 28 together, and thus close the instrumentcircuit.

In order to augment the action of the armature-spring 24, the core 15 is made hollow at its rear end to receive an auxiliary armaturespring 38. arranged to urge rearwardly an armature-retracting plunger 39, opposed to the armature. as shown in Fig. 1. and preferably having a covering of some soft material. The opposite ends ofthc magnet-coil 16 are preferably covered by hard rubber or other suitable hcads 40. To accommodate the variation dicated in Fig. 3. The line-wiresa I: are carried into the rear compartment 3 of the instrument and are connected to the binding-posts c and (i, mounted on the wall 2. Fromthc i post (1 connection is made with one terminal of the magnet-coil 16, the other terminal of which is wired to the binding-post 30 of the 5 movable circuit-closer contact 28. The post cis wired to a binding-post 23, constituting the hxed contact of the interrupter. Thus it will be seen that both the circuit-closer and the interrupter must be closed in order to energize the magnet-coil.

The operation of the instrument shown in the first seven figures of the drawings is as follows: The head-band being placed upon the head with the earpiece at the ear, the contacts- 27 and 28 will be brought together, thus closing the circuitthrough the instrument. It the current is of low amperage, the instrument may be used in the ordinary manner as a receiver, the electrical undulations cflectcd by the vibrations of the transmitter-diaphragm varying the attractive power of the magnet Y13, and thus causing the vibration of the diaphragm to reproduce the sounds uttered adjacent to the transmitter. If, however, the current is of high amperage, both the diaphragm 9 and the armature 25 will be attracted by the opposite ends of the magnet. This attraction of the armature will cause the circuit to be interrupted by the separation of the interrupter-contacts 22 and 23, and the magnet thus becominginactive the diaphragm will spring back and the armature will also move back to close the interrupter. and thus restore the circuit, which will be similarly opened and closed in quick succession as long as the instrument is connected with a suitable source of electrical energy and the circuit-closer maintained in the closed position. When a current of high amperage is utilized and the interrupter thus brought into play, the instrument is adapted for use as -a massage device, the ordinary vibrations of the diaphragm being greatly magnified, so that the vibrations transmitted to the drum of the ear will be sullicicntly intense and the circulation of air through the car and nasal passages sufiiciently marked to constitute a massage, which has been found highly efiicicnt, particularly when the patient is sufi'ering from catarr'nal deafness.

\Vhilcl consider the magnet shown in Fig. 4 and having double-ended concentric polepieces to be preferable, other forms of magnet may be employed. For instance, in Fig.

'8 of the drawings I have shown a portion of the instrument equipped with a magnet comprising a pair ot'angular pole-pieces 1' and f.

surrounded by separate coils and l: and connected bya screw passing through an interposed soft-rubber insulation 1', the pole-pieces being in turn secured to the casing by a screw lland similar soft-rubberinsulation '1 being interposed between the pole-pieces and casing, as shown. posed opposite thelaterally-extended rear ends of the pole-pieces 1' and f and is arranged to operate the interrupter n. The circuit is controlled by a circuit-closer, as in the form of invention previously described,

'and the method of wiring is clearly shown in The armature m is d1s- Fig. 9. In Fig. is shown still another form of the magnet interposed between a pair of diaphraguis g2 and q for use in a double receiver, of which many types are. in use,
